Jakarta. Investigators from Indonesia's antigraft agency, the Corruption Eradication Commission or KPK, pressed ahead on Tuesday (16/01) with its probe into Anang Sugiana Sudihardjo, the second businessman to be named as a suspect in the multimillion dollar e-KTP graft case.

Anang, who has been in KPK's detention, owned one of the companies in a consortium that won the lucrative contract for the e-KTP project.

Investigators have already summoned several lawmakers and government officials to testify against Anang in recent months.

On Tuesday, the KPK summoned a National Awakening Party (PKB) lawmaker to be interrogated about the businessman. The questioning eventually lasted three hours.

Abdul Malik Haramain said he had never known Anang. Abdul was a member of the House of Representatives' Commission II that passed the project in the parliament.

"I never knew Anang, I still don't," Abdul told reporters at KPK headquarters in Jakarta.

Abdul also denied allegations that he received $37,000 in kickbacks from the Rp 5.9 trillion ($442.5 million) project.

The accusations were originally made in an indictment against former Home Ministry officials Irman and Sugiharto, who have already been convicted in the case.

Several other former members of the House of Representatives, including North Sulawesi governor Olly Dondokambey, a politician from the Indonesian Democratic Party of Struggle (PDI-P), Central Java governor Ganjar Pranowo, also of PDI-P, former House speakers Marzuki Alie of the Democratic Party and Setya Novanto of Golkar, have also testified against Anang.

Setya, who allegedly received $7.3 million in kickbacks, is standing trial.

Another businessman, Andi Agustinus, also known as Andi Narogong, has been sentenced to eight years in prison for his involvement in the graft case, which resulted in a Rp 2.3 trillion loss for the state.
